Excerpt from Google Blog:
Today, Google launched a WiFi network in our hometown of Mountain View. Radios hanging on lampposts throughout the city are now broadcasting a "GoogleWiFi" wireless (802.11b/g) signal that brings wireless Internet access to the city's residents, businesses, and visitors. All anyone needs is a laptop or other wireless-enabled device and a web browser to get online. Then Mountain View users can select the "GoogleWiFi" signal, open their web browser and sign in with a free Google Account. To learn more about the network's coverage area and the location of the WiFi radios, we've published a map. …
Another goal of this network is to promote alternative access technologies by using Mountain View as an example for organizations considering investments in the WiFi arena. We think successful mesh wireless deployments will promote competition, create cheaper access alternatives, and (if done correctly) foster open, standards-compliant platforms for content and service providers to showcase their applications without the hassle of the traditional walled-garden approach.
